Model number is ECP3220J. Purchased from Amazon in April 2023. Used about 2-3 times a month for the past year. Descaling was performed once every 3-4 months. The included tamper was unusable and has been disposed of. A genuine, separately purchased tamper will be included. I have confirmed that all functions are working properly before listing. It is generally clean, but there are some stains that couldn't be removed by cleaning and some scratches from normal use. Thank you for looking.
